""Ground Zero"" Energy Surplus

Pyroclastic Flows

A volcanic and nuclear energy release phenomenon

What defines the phenomenon known as a pyroclastic flow?
  • Their temperature is greater than the surrounding air.
  • They flow as separate, denser, heavier-than-air fluids.
  • They have well-defined, cauliflowery-looking, expanding boundaries.

  • Their creation and expansion requires tremendous amounts of energy.
  • In Earth's atmosphere, they've only ever been known to accompany volcanic eruptions and, more recently, nuclear detonations.
Their thermal energy, plus tiny suspended (aerosol) solid particles, enables them to temporarily suspend heavier-than-air solids (debris) within them.

The movement of their boundaries is governed by wind, slope (being heavier than air, they flow downhill), and -- the primary driver for the WTC flows -- thermal expansion.

WARNING:

Disinformers are spreading the false belief that since pyroclastic flows that accompany volcanic eruptions can contain tiny suspended still-sputtering globs of magma, which can set things ablaze, and because that didn't happen at ""Ground Zero"", that therefore anyone who says that there were pyroclastic flows at GZ is wrong and can simply be ignored -- even though that means ignoring so much highly-unconventional, highly-revealing GZ evidence. (Which is fine with the disinformers, who are happiest when all valid possibilities and big-lie-busting pieces of evidence go unnoticed, unaddressed or dismissed, in favor of popularized impossible/meaningless BS/noise, leading to a hopeless sense of endless enigma...)

There are many nice pictures of huge, impressive-looking pyroclastic flows @ GZ. To publicly deny or downplay their significance is to disinform. To say that a pyroclastic flow didn't set people's hair on fire as its distinct outer boundary chased them down the street is to miss (or, depending upon intent, to divert attention from) the point.


As you're about to see, most of the ground-level images and TV videos barely hinted (the image below was released in 2010) at the scope and scale of the spectacular flow(s):
